Abstract
A method and control apparatus for the correction of a mathematically determined torque in the drive train of a motor vehicle, in which a recognition signal for distinguishing between automatic and manual transmissions is produced and motor and transmission operating states (selected in accord with the recognition signal) in which the actual torque applied to the crankshaft is equal to zero are established. When the motor and transmission operating states are reached, the mathematically determined torque associated with the operating states is compared to the actual (zero) torque, and the difference between the mathematically determined torque and the actual torque is used as a control factor for the correction of additional computed torques.
